PFAS in Vézilly's tap water: 2 ng/L, 4x our 0.5 ng/L benchmark

Last PFAS check: · Source: Hub'eau

PFAS in drinking water

4× above our health benchmark

Amount found in the water 2 ng/L 0.002 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

0.5 ng/L is our benchmark, not an official limit. Same EFSA method as Sweden, Denmark and the Netherlands, but stricter. It's a yearly average, compared here with the latest check.

Sample taken in Fère-en-Tardenois, on the same distribution network as Vézilly (UDI DE FERE EN TARDENOIS). The health authority samples one tap per network; a network carries the same treated water everywhere.

More about this result

The US also limits PFOA and PFOS to 4 ng/L each, per substance.

Substances below the detection limit count as 0, so the real total may be higher.

One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

More PFAS than in 85% of the cities we track

In Vézilly, the 4 most closely watched PFAS (PFAS-4) add up to 2 ng/L (0.002 µg/L) at the latest PFAS check on 20 January 2026. That's 4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 2 ng/L (0.002 µg/L), below the EU legal limit (100 ng/L). Sampled in Fère-en-Tardenois, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions

Is tap water in Vézilly safe to drink?

Yes. At the check on 29 April 2026, the tap water in Vézilly was within every limit tested. Outside a reference value: Turbidity 2.8 NFU on 29 April 2026 (reference ≤ 2 NFU). These are indicator parameters with reference values, not legal limits. “Eau d’alimentation conforme aux limites de qualité en vigueur mais non satisfaisante à la référence de qualité pour le paramètre turbidit é. Il est demandé de remédier à la situation de non-conformité constat ée. En attendant, l'eau reste consommable.”

How high are PFAS levels in Vézilly's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 2 ng/L. The EU limit is 100 ng/L, so this water is at 2 % of the limit. (below the EU limit)

Does the water in Vézilly also meet the strictest limits in Europe?

Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 2 ng/L stays below.

How hard is the water in Vézilly?

The water hardness in Vézilly is 46.7 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 12 September 2026.
